Can you assist me in answering this?

(this is not graded but, rather, an excersice conducive to acquisition).

Step 1

The range for the given data is given and calculated as follows:

Here, *n* is the number of observations. Hence, ** n is 15**.

The mean is calculated below.

Step 2

The sample variance is calculated below.

The sample standard deviation is calculated below.

Step 3

The first quartile can be computed using Excel formula = QUARTILE (A2:A16, 1).

Thus, the value of the first quartile is 65.

The third quartile can be computed using Excel formula = QUARTILE (A2:A16, 3).

Thus, the value of the third quartile is 295.

The interquartile range is computed as follows:
